Adblue joys 300miles left

I am getting sick of adblue. I have 300 miles almost 250 left. Thinking it’s the level sensor being confused as I overfilled. I’m going to ring VW to recalibrate the sensor. Has anybody had this done? If so how much am I looking at?
I was hoping driving it would get it to sort itself out but I’m getting very nervous.
Do you think it’s worth blasting down the motorway this evening for 100 leaving 150 just incase or just bite the bullet and wait for VW?

Most local garages say delete the adblue but I’m thinking of selling the van.
 
I don’t think you have anything to lose taking it for a run. When I had the 650 to no restart it did reset itself after a run of about 50 miles
 
when did you overfill it?

did the adlue level not reset to full? . . .

did it just keep dropping?

if so that might be cable damage to the adblue tank?

more common than you think.
 
The adblue light popped on then didn’t go out when filled and yes I did see overfill it. However after a few hundred miles it went out. Then a few hundred later came back on. Down to 150 now. Did a good motorway run but didn’t sort itself.
Can you see the cable if you lay under the van?
 
I thought I would post an update about the issue just incase it helps anybody in the future.
no garage wanted to deal with the ab blue and some wanted to do an ad blue delete. In the end I rang VW and they couldn't get the van in until the end of May.
The woman informed me that they see recovered vehicles within 48 hours.
So I rang the RAC and said the van won't start in 150miles please help. They came out tried to fix the issue but no luck. The RAC mechanic was more than happy to take the van to VW for me.
VW rang me the next night after diagnosing and said that it was EGR related.
They calibrated the ad blue tank, did an EGR flash (not really sure what they did) and ECU update.
all in 4 days without a van and £700 lighter.

Drove the van home and it feels like a new van. Very happy.
 
Mine did this a few weeks ago coming out of the airport after a week away, driving onto the M60 ad blue warning came on saying 650 miles I drove home and filled up the diesel and ad blue at the same time the, started the engine fuel needle shot up to full ad blue stayed at 650 miles, then over the week d ropped to 600 then 550 then 500:- took it for a run to the coast run on the following Sunday 70 odd miles each way just kept dropping then just setting off home maybe done 5 miles and it corrected. :

Please bear with me on this, I know it looks a bit long-winded, but I think it’s worth having a bit of background detail….

My van is the EU6 102 engine with adblue.

Sometime in June the dreaded flashing coil light made an appearance one afternoon when I’d just started the van and I was leaving work! During that journey to drop something off the van was running on limited power. When I restarted the van, the fault had disappeared and all was back to normal for my journey home…. and to be fair, I’ve had no faults since, but after reading the endless nightmare stories on this forum + previous personal experience with a blocked/failed EGR valve, this got me worried that it might be EGR problems?

I contacted @Dav-Tec (Chris) who by now had done a number of very successful jobs/upgrade’s on my van to see if he could work his magic with a possible EGR delete? Unbeknown to me, @Texxaco (Pete) had been having similar issues with his stunner of a T6 and had already had the @Dav-Tec treatment in the way of a EGR and ADBLUE ‘solution’!

At the T6Forum summer camp meet in July, Chris kindly scanned my van and found that the fault was actually with the adblue system and not the devil’s work EGR as I’d suspected…. either way, I wanted the EGR sorting! So I got booked in with Chris to have a custom remap which would include the same EGR and adblue ‘solution’ as Pete’s van.

On the day of the remap, Chris did a scan as he always does prior to any work…. goes through any fault codes with me and when looking back at previous scan’s, Chris discovered that this adblue fault had history and was showing up on most of the previous scan’s. I told Chris as well that I’d very recently noticed the smell of diesel fumes on startup…. not necessarily in the cab, just in general around the van and when we went out on the first data logging run it was clear that something wasn’t quite right?

When we got back to Dav-Tec HQ, Chris found that the rear EGR pipe was split and exhaust gases were p#ssing out into the engine bay and this was causing the boost pressure problem. No problem for Chris, he removed the split pipe, fabricated a couple of ‘delete’ plates from some sheet steel, refitted the lot and we went out on another data logging run. Much better (near perfect) results meant that a new custom map could be written to include the EGR ‘solution’ and away I went.

I’ve been driving around with the new map now for a week…. to and from work and the usual runs and roads so that I could get a comparison with what I had before (which by the way was a generic Pendle map installed by Leighton Vans). Don’t get me wrong, I had no complaints or issues with the previous map…. I’d had it on there for over two years, but because of the running issues, I needed a ‘solution’ and Chris’s custom remap ticked all my boxes.

I couldn’t be happier with the results of the custom map supplied by Chris…. the engine runs free and smooth even from a cold start up and pulls progressively, purposely and smoothly throughout.

I want to thank Chris for going above and beyond as he always does…. and also his very patient wife Tracy for putting up with me on that Saturday!

Cheers, Matt :thumbsup:

Thats how mine started. Always sorted itself out but not this time.
